A fault repair device for underground coal mines

Abstract

This utility model discloses a fault repair device for underground coal mines, comprising a first base frame and a second base frame. A first top plate is movably mounted on the telescopic end of a hydraulic cylinder on the first base frame, and a second top plate is movably mounted on the telescopic end of a hydraulic cylinder on the second base frame. Through the design of the first base frame, second base frame, first top plate, second top plate, and hydraulic cylinder, the hydraulic cylinder can push the first and second top plates, allowing them to rise and fall, enabling them to contact the fault. This allows the device to quickly adjust the height of the fault. The cooperation between the first and second top plates allows for adjustment of the distance between the first and second base frames, enabling the device to quickly adjust the width of the fault. This provides effective support for the fault, allowing for rapid fault support and reducing the labor intensity of workers.

Description

Technical Field

[0001] This utility model relates to the field of coal mine support technology, specifically a fault repair device for underground coal mines. Background Technology

[0002] Faults are geological discontinuities in coal seams, which often lead to a decrease in the stability of the coal seam and pose safety hazards to coal mining. Underground fault repair devices in coal mines enhance the strength of the coal seam in the fault area through support and other means, preventing the coal seam from collapsing or shifting during mining and ensuring the stability of the mine.

[0003] Currently, existing underground fault repair devices in coal mines are not adjustable and lack the necessary adjustment functions. As a result, they cannot quickly adapt to and effectively support faults of different widths and heights, requiring longer preparation time and higher labor intensity, which reduces work efficiency. Therefore, we need to propose an underground fault repair device for coal mines. Utility Model Content
